ALLEGAN COUNTY -- A routine traffic stop late Monday led to a cocaine drug bust, a police pursuit on I-196 near Saugatuck and the recovery of two stolen vehicles.

Allegan County sheriff's deputies said an officer stopped a vehicle about 11:40 p.m. on I-196 in Laketown Township and noticed what appeared to be a bag of cocaine inside.

Once the officer retrieved the bag, the driver of the car sped away.

The officer pursued, chasing the vehicle on I-196 and then onto M-89. Near 66th Street, state police managed to deploy spike strips and deflate the car's tires.

A woman who was driving the car, a stolen rental vehicle, was arrested there. But a male passenger fled into the darkness.

About three hours later, a person matching the description of the male passenger entered the BP gas station in Fennville. The station clerk called 911 and gave police a description of the vehicle the man was driving.

Police soon after arrested him at the Holland area residence of the female arrested earlier. Deputies discovered he had stolen the vehicle near M-89 and 66th Street, where he bailed from the first vehicle.

Police seized more than two ounces of cocaine and more than $500 in cash during the incident.

The passenger, from Chicago, is held in the Allegan County jail on a drug charge and auto theft.
